Folding box or receptacle



3 A. J. TANNER FOLDING BOX OR RECEPTACLE Filed Dec. 20, 1929 Patented Nov. 24, 1931' UNITED STATES PATENT OFFIE ARNOLD J. TANNER, OF NORTH HAVEN, CONNECTICUT FOLDING Box on nncnrrnonn Application filed December 2t), 1929. Serial No. 415,443.

which consumes the minimunr amount of material and which may be readily assembled from the flat blank and retentively held W in the folded position by means which are sell-acting, meaning that no gluing is required nor are there anyinter-lockingtongues or similar devices which are required to be engaged, in fact the box, when assembled, is held in that position by friction means entirely.

The improved box or carton may be employed with or without a cover and when a cover is employed the same may be assembled to told on itself to provide'a display card.

lln another embodiment of the invention the improved carton or receptacle may be employed as a saucer or tray for a flower pot, for example such as described in a copending application Serial No. 394,4?9. lit will be noted in the latter-use of the invention, the tray or receptacle made accordingly thereto, is practically water-tight tor the corners oi the receptacle are water-tight and when the receptacle is made of water-proof mate rial, this tightness against the leakage of water is of particular advantage in the use mentioned and also for other uses such for example as a tray or receptacle employed for containing ice-cream or the like.

The several embodiments of the invention will be described hereinafter with reference to the accompanying drawingswherein- Figure l is a perspective vlew showlng the improved box or carton with a cover and "which latter is in its open position so folded as to provide a display or advertising means at the back of the box;

Figure 2 is a sectional view taken on the line 22 of Figure 1;

Figure 3 is a plan view of a blank of which a box and cover therefor is constructed; and Figure 4 is a perspective view showing the improved receptacle in use as a saucer for a flower pot.

Referring to the drawings, more particularly to Figure 3, herein the blank of which the complete box and cover is composed, comprises the body portion 1 and extension 2 therefrom. The body blank is creased on the on lines 3 to define sections 44 and 5-5. The sections 4- 1 form the outer side walls of the receptacle. One section 5 forms the front wall and the opposite section 5 forms the back wall of the receptacle. Corner sections 6 contu nect the sections 4-4 and 55 together and these sections 6 are diagonally scored on the lines 7 so as to allow a bellows-like fold of the said sections. Flaps 88 are connected to the sections 4-4 and these flaps are an ranged to told inwardly to form double side walls lying over the folded-in corner sections 7 and which sections -told against the side walls. The flaps 8-8 are tapered with expanding free ends so as to conform with the to inwardly sloping angular corners of the receptacle.

The corner sections 6, referred to hereinbeiore, also fold'on lines 99 where they are connected to the sections H and 55 in such a way that the side walls are tapered and inwardly inclined from the bottom upwardly. With this arrangement the side walls and also the front and back walls stand out of perpendicular position relatively to the bot- W tom of the receptacle, as shown in the set-up position of the box in Figure l. The flaps 8-8 are slightly greater in width than the side walls, therefore, when said flaps are folded inwardly over the folded corner sec- 85 tions 6, as shown in Figure 2, the lower edges of said flaps will irictionally engage the upper surface of the bottom 10 and thereby, due also to the inward slant of the side Walls, said flaps are retentively held in the foldedin position. With this retention means the box or receptacle is firmly held in its set up position.

The extension 2 is connected to the body by means of the section 5 forming the back 95 wall of the receptacle. This extension forms the cover for the receptacle and is retentively held in its closed position by the tuck-in side flaps 11 and tuck-in flap 12. Said extension is cut and scored on the line 13 so as to fold on itself to form a display device which is folded in the position shown in Figure 1 wherein said side flaps 11 are preferably folded in to improve the appearance of the display. Means comprising ears or pieces 14 cut out of the flaps 8-8 lie in a horizontal position to engage the bottom of the folded cover to retain the same in the raised display position. I

In Figure 4 a modified use of the improved receptacle is shown and herein the receptacle is in the form of a saucer 15 which is used with a flower pot 16, for example. In this application of invention the receptacle is substantially the same as the other example with the exception that the cover extension member 2 is omitted.

The improved structure hereinbefore described produces a receptacle or carton havin the maximum rigidity that can be ob tamed with the material of which the article is composed, and as previously stated, there are no inter-locking tongues or slits which leave openings at the corners or elsewhere, therefore, the carton or receptacle is practically water-tight and to get full advantage of this feature, it is obvious-that the article may be composed of water-proof material.

Various modifications may be made in carrying out the constructional details of the invention hereinbefore described or in the application of the invention, wholly or part ly, and it is to be understood that any modification coming fairly within the terms of the appended claims shall be covered thereby.

I claim:

1. A receptacleof the class described having inwardly sloping single walls and flaps connected to oppositely disposed walls arranged to be folded inwardly and to be selfretained in the folded position whereby through friction alone said receptacle is maintained in its folded or set up position.

2. A receptacle of the class described having inwardly sloping single or inner walls, flaps extending from oppositely disposed walls arranged to be folded inwardly to provide double walls and engaging means comprising expanded ends of said flaps whereby the receptacle is maintained in its folded position.

3. A receptacle of the class described having a bottom, side, end and back walls, said walls sloping inwardly, said end walls having flaps connected thereto arranged to be folded inwardly and retained in the folded position by forming frictional self-retentive means; and an extension from said back wall providing a cover for the reduced open top of said receptacle.

4. A receptacle of the class described having a bottom, side, end and back walls, said walls sloping inwardly, said end walls having flaps connected thereto arranged to be folded inwardly and retained in the folded position by frictional restraint produced due to the inward inclination of said walls.

5. A receptacle of the class described composed of a single blank havin defined sec tions forming the side, back an end walls of the receptacle; corner pieces connecting said sections, said corner pieces being arranged to fold in an inwardly inclined angle, said sections being arranged to fold to provide inwardly inclined walls; flaps connected to said side walls arranged to fold over the respective wall so as to over-lie said folded end corner pieces and said folded flaps, due to the inwardly inclination of the side walls being frictionally engaged whereby the receptacle is maintained in its folded or set up position.

6. A receptacle of the class described composed of a single blank having defined sections forming the side, back and end walls of the receptacle, corner pieces connecting said sections, said corner pieces being arranged to fold in an inwardly inclined angle, said sections being arranged to fold to provide inwardly inclined walls; flaps connected to said side walls arranged to fold over the respective wall so as to over-lie said folded corner pieces, said folded flaps due to the inwardly inclination of the side walls being frictionally engaged whereby the receptacle is maintained in its folded or set up posltion; an extension from said back wall providing a cover for the receptacle, means for retaining said cover in its closed position and means whereby said cover is folded on itself and retained in a position-to provide a display device.
